Abstract

The invention relates to a thermoplastic rubber foam material FRB and a preparation method thereof, and belongs to the field of new chemical materials.The thermoplastic rubber foam material FRB is prepared from, by weight, 30-70 parts of styrene-butadiene block copolymer (SBS), 5-30 parts of ethylene-octene block copolymer (OBC), 3-10 parts of styrene-butadiene copolymer, 3-10 parts of polystyrene (PS), 5-30 parts of white oil, 3-8 parts of white carbon black, 3-8 parts of filler, 0.5-3 parts of microsphere foaming agent, 0.5-3 parts of chemical foaming agent, 1-3 parts of silicone elastomer and 2-5 parts of cell regulator.

Description

technical field [0001] The invention relates to a thermoplastic rubber foam material FRB and a preparation method thereof, belonging to the field of new materials. Background technique [0002] The sole material in the prior art comprises rubber, TPR, EVA foam material, polyurethane foam material TPU and PVC material etc. [0003] Rubber material is the oldest sole material, characterized by good elasticity, wear resistance, anti-slip, cold resistance, oil resistance, etc., but the density is too high (1.1-1.4g / cm 3 ), and the vulcanization production process is very unenvironmental, the labor intensity of the workers is high, the production capacity is low, the soles have a strong smell, they will spit frost when they are cold, they are easy to age and harden, and the waste cannot be recycled. [0004] TPR material is the main sole material, fitness equipment material and toy material, but there are still too high density (generally 0.8-1.2g / cm 3 ), and the tortuosity and...
